How to Prepare for the Test

You must sign an informed consent form before you have a bladder biopsy. Usually you are asked to urinate just before the procedure. You may also be asked to take an antibiotic before the procedure.

For infants and children, the preparation you can provide for this test depends on your child's age, previous experiences, and level of trust. For general information regarding how you can prepare your child, see the following topics:

How the Test Will Feel

There may be slight discomfort as the cystoscope (a lighted instrument used to look at the bladder) is passed through your urethra into your bladder. You will feel an uncomfortable sensation -- similar to a strong urge to urinate -- when the fluid has filled your bladder.

You may feel a pinch during the biopsy. There may be a burning sensation when the blood vessels are sealed to stop bleeding (cauterized).

After the cystoscope is removed, your urethra may be sore. You may experience a burning sensation during urination for a day or two.

Sometimes when the suspicious area is larger, you will need general or spinal anesthesia to remove the area in question.

Why the Test is Performed

This test is most often performed to check for cancer of the bladder or urethra.

Normal Results

The bladder wall is smooth. The bladder is of a normal size, shape, and position. There are no obstructions, growths, or stones.

What Abnormal Results Mean

The presence of cancer cells indicates bladder cancer. The type of cancer can be determined from the biopsy sample.
